Hi Lukas,
the hoster provides its own kernel for the dedicated servers, i've
updated via netboot to the 3.8.13 hoster kernel. So it's not the distro
kernel nor kernel.org.
For the load, how can i know if it's kernel or user space ?
I have the load average with the top command.
%CPU ( %us, %sy ... )is the same than before, only the load average has
increased.
Thanks.

Hi Arnall!
Yesterday OVH asked their customers to
update the kernel to 3.8.13 ( due to a local linux root exploit in
2.6.37 to 3.8.8 ).
I've done the update (old kernel = 3.2.13) but now the load of our
haproxy servers has increased ( x 4 ). It's still reasonable but i would
like to know if i can provide any informations to know why.
Debian is backporting those fixes to their distro kernel, there is no
need for you to upgrade to a kernel.org kernel - in fact this is a
pretty major step. Doesn't the latest debian kernel update [1] contain
the fix?
Did the load increase in kernel or user space?

Lukas
